It looks like some variant of the Model 1858. More detailed photos might help with the identification.
Neither of those that you posted have the hinged ramrod!Also found this picture which looks the same but no name associated with it.

By George (kind of apropos), I think that you've got it!It appears to be a British Beaumont-Adams, first made in the 1850's. This picture is not identical to yours, but there were several different models. Fun facts: A.442 caliber version was bought by the armies of the UK, Holland and Russia. The Union Army bought a bunch in .36 at the beginning of the Civil War. they were popular enough that they forced Sam Colt to shut down his UK operation.

Both of the ones in the two links I posted have a hinged ramrod and hinges downwards. The 3rd one I posted you can't see because it would be on the other side but otherwise looks almost identical even the same style scroll work, bobbed hammer and trigger guard. The one JM posted the ram rod hinges upwards, has a hammer spur and trigger guard is different. All appear to use the Adams double action patent except for the lone picture with no name or description but that one also looks the closest.Neither of those that you posted have the hinged ramrod!

FWIW, I'm not a vintage gun expert. I found the information on Google in about 15 min., but I admit I've gotten pretty good at it because I'm very inquisitive by nature and being retired I have a lot of time on my hands. This is not throwing any shade at you at all, sometimes I strike out completely on Google. But I got a kick out being able to find it, so thanks for the challenge!Thanks, great info. I could have saved many hours on Google if I came here first. My grandfather has a colt of the same era I look forward to comparing the two side by side. Thanks to everyone here for their input. I will post some better photos along with our other antique rifles and revolvers when I get a chance.
